CROSS REFERENCE TO RELATED APPLICATION

This application is a division of U.S. patent application Ser. No. 13/492,210, filed Jun. 8, 2012, now U.S. Pat. No. 9,672,519, which is hereby incorporated by reference herein in its entirety.

FIELD OF THE INVENTION

The invention relates generally to a software radio that can communicate with a financial institution over more than one radio network, and in particular to a mobile device having a software radio for securely passing financial information between a customer and a financial services firm.

BACKGROUND

Software radio is an emerging technology in wireless communication services. Transmitters and receivers that allow electronic communications to be transmitted using the radio frequency (RF) spectrum are moved from hardware to software. A software radio can be a radio that is substantially defined in software and whose physical layer behavior can be significantly altered through changes to its software. A software radio can define in software its modulation, error correction, and encryption processes, can exhibit some control over the RF hardware, and can be reprogrammed.

SUMMARY OF THE INVENTION

The invention, in various embodiments, features a software radio that can communicate with a financial institution over more than one radio network. A customer of the financial institution can use a mobile device having a software radio to securely pass financial information to the institution. The mobile device can encrypt information and pass it to the financial institution, which has a computing system capable of receiving the information, decrypting the information and carrying out a financial transaction based on the information.

Because information related to a transaction is being transmitted over more than one network, a hacker cannot tap into or listen to one network and retrieve all of the information needed to perform an identity theft or fraudulent transaction. For example, encryption information can be transmitted on one network, while secure data is transmitted on a separate and independent network.

Traditionally, radios have been implemented entirely in hardware, with new waveforms added by integrating new hardware. Wireless handsets can support wireless standards: GSM, GPRS, EDGE, WCDMA, HSDPA, Long Term Evolution (LTE), 4G, GPS, mobile TV, Wi-Fi, Bluetooth, WiMAX and UWB. A software radio can support multiple waveforms by re-using the same hardware while changing its parameters in software.

A software radio allows multiple radio standards to operate on common radio frequency hardware, ensuring compatibility among legacy, current, and evolving wireless communication technologies. A software radio is capable of changing its operation by dynamically loading a radio configuration over the air. With different configurations, the device can operate using different wireless communication technologies while having a single transceiver.

In one aspect, there is a method including identifying, by a computing device having a software radio, two or more radio networks available for communication with a financial institution. The method includes transmitting, by the computing device, first information related to a financial transaction over the first radio network to the financial institution; tuning, by the computing device, the software radio from the first radio network to a second radio network independent from the first radio network; and transmitting, by the computing device, second information related to the financial transaction over the second radio network to the financial institution. A server of the financial institution receives the first information and the second information to carry out the financial transaction.

In another aspect, there is a computer program product, tangibly embodied in a machine readable storage device of a computing device having a software radio. The computer program product includes instructions being operable to cause a data processing apparatus of the computing device to identify two or more radio networks available for communication with a financial institution, transmit first information related to a financial transaction over a first radio network to the financial institution, tune the software radio from the first radio network to a second radio network independent from the first radio network, and transmit second information related to the financial transaction over the second radio network to the financial institution. A server of the financial institution receives the first information and the second information to carry out the financial transaction.

In yet another aspect, there is a computing system of a financial institution. The computing system includes a key gateway in communication with a computing device over a first radio network, a data gateway in communication with the computing device over a second radio network independent from the first radio network, and a key storage facility in communication with the key gateway and the data gateway. The computing device has a software radio. The key gateway (A) receives an application level encryption key from the computing device, (B) stores the application level encryption key in the key storage facility, and (C) transmits, to the computing device, a key index indicating a location of the application level encryption key on the key storage facility. The data gateway (A) receives (i) data encrypted, by the computing device, using the application level encryption key and (ii) the key index, (B) retrieves the application level encryption key from the key storage facility, and (C) decrypts the data using the application level encryption key. The decrypted data is transmitted to a server of the financial institution to carry out a financial transaction.

In still another aspect, there is a method including receiving, over a first radio network, by a key gateway of a financial institution in communication with a computing device having a software radio, an application level encryption key from the computing device; storing, by the key gateway, the application level encryption key in a key storage facility; transmitting, to the computing device, by the key gateway, a key index indicating a location of the application level encryption key on the key storage facility; and receiving, over a second radio network, by a data gateway in communication with the computing device over a second radio network, (i) data encrypted, by the computing device, using the application level encryption key and (ii) the key index. The first radio network is independent from the second radio network. The method further includes retrieving, by the data gateway, the application level encryption key from the key storage facility; decrypting, by the data gateway, the data using the application level encryption key; and transmitting, to a server of the financial institution, by the data gateway, the decrypted data to carry out a financial transaction.

In other examples, any of the aspects above, or any apparatus, system or device, or method, process or technique, described herein, can include one or more of the following features.

The software radio can be substantially defined in software of a mobile device. In various embodiments, the first information is an application level encryption key. The second information can be (i) data encrypted using an application level encryption key and (ii) a key index indicating a location of the application level encryption key on the server of the financial institution.

In certain embodiments, the method includes receiving, by the computing device, a key index from the server of the financial institution, where the key index indicates a location of an application level encryption key on the server of the financial institution; encrypting, by the computing device, data using the application level encryption key; and transmitting, by the computing device, the second information to the financial institution, wherein the second information includes the data and the key index.

In some embodiments, a first rating for the first radio network and a second rating for the second radio network are determined to identify the first radio network as being independent from the second radio network.

In certain embodiments, a visual indicator is provided to a user of the computing device to indicate that the first radio network is independent from the second radio network, and input from the user is received to initiate transmission of the first information and the second information over the respective networks.

The first radio network being independent from the second radio network means that the networks operate on different frequencies, utilize different transmission protocols, or are operated by different carriers.

The data gateway can include a data decryption module to decrypt the data using the application level encryption key.

Other aspects and advantages of the invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrating the principles of the invention by way of example only.

DETAILED DESCRIPTION

FIG. 1 shows a system for securely passing financial information between a customer and a financial institution. The customer or user has a computing device 10 having a software radio. The computing device 10 can communicate with a computing system 14 of the financial institution over a plurality of communication channels. As shown in FIG. 1, computing device 10 and computing system 14 communicate via a first radio network 18 and a second radio network 22. The networks can include base stations for wireless communication.

The computing device 10 including the software radio can be, for example, a notebook computer 10 a, a handheld mobile device 10 b, a tablet 10 c, a desktop computer 10 d or the like. The software radio can be substantially defined in software of a mobile device. The computing device 10 can identify that two or more radio networks are available for communication with the financial institution. The first and second radio networks are independent from one another, meaning that the networks operate on different frequencies, utilize different transmission protocols, or are operated by different carriers.

The computing device 10 can transmit first information 26 related to a financial transaction over the first radio network 18 to the financial institution. The computing device 10 can tune the software radio from the first radio network 18 to the second radio network 22, and transmit second information 30 related to the financial transaction over the second radio network 22 to the financial institution. The computing system 14, or a server 32 of the computing system 14 of the financial institution, receives the first information 26 and the second information 30 to carry out the financial transaction. The first information 26 can be an application level encryption key. The second information 30 can be (i) data encrypted using the application level encryption key and (ii) a key index indicating a location of the application level encryption key on a server of the financial institution.

The computing system 14 of the financial institution is separated from outside networks via a firewall 34. The computing system 14 includes a key gateway 38, a data gateway 42, and a key storage facility 46. The key gateway 38 is in communication with the computing device 10 over the first radio network 18. The data gateway 42 is in communication with the computing device 10 over the second radio network 22. The key storage facility 46 is in communication with the key gateway 38 and the data gateway 42. In certain embodiments, the data gateway 42 includes a data decryption module 50.

The key gateway 38 receives an application level encryption key from the computing device 10. The application level encryption key is stored in the key storage facility 46, for example, by the key gateway 38. A key index is transmitted to the computing device 10 via the key gateway 38. The key index indicates a location of the application level encryption key on the key storage facility 46. The data gateway 42 receives (i) data encrypted, by the computing device, using the application level encryption key and (ii) the key index. The data gateway 42 retrieves the application level encryption key from the key storage facility 46, and decrypts (e.g., using the data decryption module 50) the data using the application level encryption key. The decrypted data is transmitted to a server 32 of the financial institution to carry out a financial transaction.

Examples of financial transactions include, but are not limited to buying, selling or trading securities with a brokerage service, making payments on a mortgage, transferring money from one financial account to another financial account within the same financial institution or between different financial institutions, making gifts of money of financial instruments for charitable or any other purposes, requesting participation in an initial public offering, requesting financial portfolio rebalancing, and requesting deferred actions such as a change in 401k contribution amounts.

FIG. 2 shows an example of a mobile computing device 10 including a software radio 54 substantially defined in software of the computing device 10. The computing device 10 includes a transceiver 58, memory 62 and a controller 66. The computing device 10 includes a display 70 and an input device 74.

The controller 66 can run an application to determine to which networks the device can use to transmit data and information. The display 70 can include a visual indicator 78 to indicate to the user that the radio networks are available and are independent.

The controller 66 can include a data encryption module that creates an application level encryption key and encrypts data using the application level encryption key. The controller 66 can transmit, using the software radio 54, via the transceiver 58, the key over the first network to the computing system 14. A network handshake through a standard secure protocol is used to pass the encryption key from the computing device 10 to the financial institution via the first network. Likewise, the controller 66 can receive the key index from the computing system 14 (preferably over the first network) and store the key index in memory 62. The software radio 54 can tune from the first network to the second network. The controller 66 can then retrieve the key index and data from memory 62, and transmit, using the software radio 54, via the transceiver 58, the information over the second network to the computing device 14.

In some embodiments, the controller 66 can rate the networks, so that a first network and second network can be selected. The basis for the rating is any combination of the strength, security, carrier, protocol, physical signal frequency, probability of an attack in the network, and prior history of network reliability. A first rating for the first radio network and a second rating for the second radio network can be used to determine or to identify that the first radio network is independent from the second radio network.

The input device 74 can be a touch screen or a keypad. When networks have been identified as being independent, the user can enter input via the input device 74 to initiate transmission of the first information and the second information over the respective networks.
